White Matter Changes Allow Older Brains to Learn

New research from Brown University shows that older people can learn a visual task just as well as younger ones, revealing that a significant change in the white matter of the brain takes place when the older subjects learn. Providence, Rhode Island (Brown University) — A widely presumed problem of aging is that the brain […]

New Molecular Map Reveals Genetic Origins of Autoimmune Diseases

Researchers have developed a molecular map that pinpoints genetic variants that play a role in 21 different autoimmune diseases, providing new insight into the cause of multiple sclerosis and other autoimmune diseases. Researchers at Yale, the University of California-San Francisco (UCSF), and the Broad Institute of MIT and Harvard developed a sophisticated mathematical model and […]

Decoy Drug Allows Brain to Form New Connections

New research from Stanford Bio-X scientists shows that the brains of adult mice are able to form new synapses by disabling the function of a single protein for as little as a week. This research has the potential to help adults recover from stroke and forms of blindness or to prevent the loss of connections […]

Dietary Cocoa Flavanols Reverse Age-Related Memory Decline in Healthy Older Adults

A new study from Columbia University Medical Center shows that dietary cocoa flavanols reverse age-related memory decline in healthy older adults. New York, New York — Dietary cocoa flavanols—naturally occurring bioactives found in cocoa—reversed age-related memory decline in healthy older adults, according to a study led by Columbia University Medical Center (CUMC) scientists. The study, […]

Researchers Discover Mechanism that Repairs Brain after Stroke

Working with mice, researchers from Lund University and the Karolinska Institute have discovered a previously unknown mechanism through which the brain produces new nerve cells after a stroke. The findings have been published in the journal Science. A stroke is caused by a blood clot blocking a blood vessel in the brain, which leads to […]

New MRI Technique Detects Evidence of Cognitive Decline

A new study shows that a noninvasive arterial spin labeling MRI can detect signs of cognitive decline in the brain even before symptoms appear, finding that patients who showed reduced brain perfusion at their initial exams exhibited cognitive decline at follow-up 18 months later. Oak Brook, Illinois — A magnetic resonance imaging (MRI) technique can […]

Study Shows Multitasking May Change Brain Structure

New research from the University of Sussex shows that people who frequently use several media devices at the same time have lower grey-matter density in one particular region of the brain compared to those who use just one device occasionally. Simultaneously using mobile phones, laptops and other media devices could be changing the structure of […]

Eye of Zebrafish Larva Distinguishes Between Prey and Predator

A new study from the Max Planck Institute for Medical Research reveals how the eye of a zebrafish larva can already distinguish between prey and predator. Red or green? Small or large? Fast or slow? Humans and animals rely on their visual organs to classify objects in their environment. Decisions about how we best respond […]

Brain Structure Could Predict Risky Behavior

New research shows that brain structure may predict risky behavior, revealing that those with a larger volume in a particular part of the parietal cortex were willing to take more risks than those with less volume in this part of the brain. Some people avoid risks at all costs, while others will put their wealth, […]

A New Pathway to Help Treat Perinatal Brain Injuries

A team of researchers has uncovered a new pathway to help treat perinatal brain injuries, revealing that a synthetic molecule derived from the embryo called PreImplantation Factor (sPIF) protects against neuronal death and brain injury by targeting let-7. Researchers at Yale School of Medicine and their colleagues have uncovered a new pathway to help treat […]

Chimps Outplay Humans in Brain Games

In a new study chimpanzees outplay humans in a two-player game, suggesting that chimps may have a superior memory and strategy when it comes to recalling their opponent’s choice history. We humans assume we are the smartest of all creations. In a world with over 8.7 million species, only we have the ability to understand […]

Neuroscientists Reverse Emotional Association of Memories

Neuroscientists from MIT have identified the brain circuit that controls how memories become linked with positive or negative emotions, revealing that they could reverse the emotional association of specific memories by manipulating brain cells with optogenetics. Most memories have some kind of emotion associated with them: Recalling the week you just spent at the beach […]

Neuroscientists Improve Touch Sensitivity in Mice

Neuroscientists from Brown University show that faint sensations can be made more vivid by triggering a brain rhythm that appears to shift sensory attention in mice. This newly published study provides the first direct evidence that the brain’s “gamma” rhythms have a causal role in processing the sense of touch. Providence, Rhode Island (Brown University) […]
